Specifications

Control Interface Module, Continued
The CIMBase is equipped with several LEDs that relate useful
information regarding the operating status of different interfaces. These
LEDs are shown in figure 2-6 and described in table 2-3. The CIMBase
is also equipped with certain option switches, described below, that must
be set appropriately for proper operation. Before installation, verify that
all switches are set correctly. When replacing a CIMBase verify that the
switch settings on the new board match the switch settings on the board
being removed.
CIMBase LEDs and
Options
• I
2
C Bus Pull-Up Dip Switches – These switches are set to OFF
for a particular CIM I
2
C Bus when that bus is connected directly
to the internal I
2
C distribution on the PECM-DC. They are set to
ON otherwise. There is one set of two switches for I
2
C Bus A
and another set for I
2
C Bus B (as marked on the board). Both
switches for a particular bus must be set the same.
• CPLD Spare – These switches are not used in normal operation,
and are set to OFF.
